Abstract (en)

[origin: WO0038274A1] An indirect electrical coupling for a cellular telephone antenna is created by a rotary primary antenna and a stationary paging antenna when the primary antenna is extended into an operative position. When extended, the primary antenna is positioned proximate to the secondary antenna to define an electrical coupling therebetween. Rotating the primary antenna away from the extended position automatically disengages the primary antenna from the telephone operating circuit. The antenna elements or antenna spacings provide the appropriate matching circuitry and the advancement and retraction of the primary antenna provides the switching of the matching circuitry.
